Merchants Exchange, which is based in Chicago, said it is the only electronic, demutualised, independent exchange in the US. It was founded in St Louis in 1836 and, before the rise of the Chicago Board of Trade, was the country’s leading commodities exchange. It received designation as a futures market from the Commodity Futures Trading Commission in July 2000.
The largest US energy exchanges in terms of volume are the New York Mercantile Exchange and Atlanta-based Intercontinental Exchange. Both have picked up liquidity following the demise of EnronOnline.
